This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
A[Graph A showing amount of DNA increasing linearly]
B[Graph B showing amount of DNA decreasing linearly]
C[Graph C showing amount of DNA staying constant, then doubling, remaining constant at doubled amount, then halving back to original, then remaining constant]
D[Graph D showing amount of DNA staying constant, then doubling, remaining constant at doubled amount, then halving back to original, then remaining constant]
✓ Correct answer
D: [Graph D showing amount of DNA staying constant, then doubling, remaining constant at doubled amount, then halving back to original, then remaining constant]
